[Chemical Constituents from Leaves of Liquidambar formosana].Zhong Yao Cai. 2014 Dec; 37(12):2219-21.ZY
OBJECTIVE
To study the chemical constituents of the leaves of Liquidambarformosana.
METHODS
The chemical constituents were isolated and purified by column chromatography on silicagel, Sephadex LH-20 and MPLC. Their structures were elucidated on the basis of physicochemical properties and special analysis.
RESULTS
Eight compounds were isolated from the leaves of Liquidambar formosana, whose structures were elucidated as gallic acid (1), p-hydroxy-benzoic acid (2), 3-methoxy-4-hydroxy-benzoic acid (3), 3,5-dihydroxy-4-methoxy-benzoic acid (4) kaempferol (5), 3,4-dihydroxy-benzoic acid (6), 3,4-dihydroxy-5-methoxy-benzoic acid (7) and 3β,23,29-trihydroxy-olean-12-en-28-oic acid-β-D-glucopyranosyl ester (8).
CONCLUSION
Compounds 1-8 are isolated from the leaves of Liquidambar formosana for the first time.
